I can't install dhcpcd while installing artix, read only filesystem error.

I'm on artix runit, I can't install dhcpcd because my file system is read-only. How can I fix this?

Output:

Code: [Select]
pacman -S dhcpcd

First of all, the message says you are reinstalling it (it's already installed). Secondly, the only thing that fails is post-transaction hook not the actual package. The "Failed to open file "/sys/devices/system/cpu/microcode/reload": Read-only file system" message happens if you're running from the live iso or something. That's not a bug. It really is read-only. If your root partition on a real, installed system was really read-only, you'd be running into way, way more problems than just this.

Yeah, there is a virtual file system which is mounted on /sys. During the installation, you are in chroot, and therefore your /sys is somewhat "fake" (it is bound to a "real" /sys of a real host system). This warning has nothing to do with the actual installation on the disk (which ran normally), but it is rather an artifact of being in chroot instead of real working host.
